In the experiment, an approach was made to the cause of DRP and the mechanism of it's prevention and treatmend by acupuncture. The experimental results indicated that in rat with diabetes,(1) plasma TXB2 and the ratio of TXB2 to 6-keto-PGF1α increased obviously, suggesting hyperfunction of platelet and injury to endothelial function, which tend to result in thrombosis;(2) erythrocytic filtration index increased remarkably, suggesting erythrocytic transforming and oxygen carring hypofunction, which is one of the factors leading to retinal anoxia;(3) hyperglycemia persisted, which is related to the thickening of basilar membrane of and the decrease of mural cell of retinal blood vessels;(4) serum growth hormone rose notably, which is not only one of the important factors causing basilar membrane thickening but also promotes the synthesis or Von Willebrand Factor that participates in a tendency to thrombosis.

本实验对糖尿病性视网膜病变（Diabetic Retinopathy，DRP）的成因以及针刺防治DRP的作用机理进行了探讨，实验结果表明：糖尿病大鼠（1）血浆TXB2及TXB2/6-ket0-PGF1α比值均显著升高，提示其血小板机能亢进，内皮细胞功能损伤，具有血栓形成倾向；（2）红细胞滤过指数（Filtration Index，IF）显著增高，提示其红细胞变形能力低下，携氧运行功能降低，是造成视网膜缺氧状态的因素之一；（3）呈持续高血糖状态，与视网膜血管基底膜增厚及管壁细胞减少有关；（4）血清生长激素（Growth Hormone，GH）水平明显升高，既是导致基底膜增厚的重要因素之一，又促进VWF合成，参与血栓形成倾向。

实验结果表明，高频间歇式曝气方式在抑制了硝酸细菌的活性的同时也消除了亚硝酸盐浓度和pH大幅波动对亚硝酸细菌和厌氧氨氧化细菌活性的影响；在曝气阶段，溶解氧浓度被控制在1.2～1.4mg·L-1，亚硝酸细菌成为主体细菌，亚硝酸盐积累；在缺氧阶段，随着溶解氧浓度迅速降低，厌氧氨氧化细菌成为优势菌种，曝气阶段积累的亚硝酸盐与氨氮同时被去除。

After moving into ICU, former diseases,invasive testings and treatments, daily nursing, long-term immobilization can causepain to the patient; continuous noisy, continuous surrounding light, various stimuli,sleep disturbances, worry about his own disease can cause anxiety to the patient;extreme anxiety, pain, phrenitis, side effects of drugs or interaction of drugs, anoxia,low blood pressure, low blood glucose, drug or alcohol withdrawal response cancause mania, which all can result in strong stress response, human-machine resist,removal of devices and canals involuntarily.

病人进入ICU后可因原发疾病、侵入性检查与治疗、日常护理、长期制动等因素导致疼痛；可因持续噪音、持续的周围灯光、各种刺激、睡眠干扰、对自身疾病的担心等因素导致焦虑；还可因极度焦虑、疼痛、谵妄，药物的副作用或相互作用，缺氧、低血压、低血糖等生理紊乱，酒精或药物的戒断反应等因素导致躁动。

BACKGROUND: The copper-superoxide dismutase can not play an effective role in free radical-scavenging in the process of hypoxia or reaeration because of blood-brain barrier, whether the treating effect can be enhanced by chitosan nanoparticles is uncertain.

背景：由于血脑屏障的存在，铜超氧化物歧化酶在临床应用中往往达不到其在体外对中枢神经细胞缺氧、复氧过程中的自由基清除效果。那么能不能利用壳聚糖纳米粒这一种新的基因载体来增强铜超氧化物歧化酶的治疗效果呢？

Based on the experience of Rice model preparation, neonatal rat models with both of HI and hyperglycemia or hypoglycemia were prepared by either injection of 25% glucose or fasting.

在已成功建立了缺氧缺血新生大鼠模型丰富经验的基础上，选用浓度为25％的葡萄糖，通过调节不同的注射次数或在HI前禁食12小时，建立了相应的HI合并高、低血糖模型。

Known differential expression gene: In the 46 points of known differential expression gene, there were down - regulate gene expression 41 points and up- regulate gene expression 5 points; twenty - eight genes related to hypoxia/reoxygenation had not been reported and 18 genes had been reported.

NADPH oxidase inhibitor, diphenylene iodonium chloride (DPI, 10 μmol/L), abolished histamine-stimulated calcium oscillations both in normoxic and posthypoxic PAECs.(3) Xanthine oxidase inhibitor, oxypurinol (100 μmol/L), did not affect the calcium oscillation kequency in normoxic PAECs. However, it significantly decreased the elevation of calcium oscillation frequency in posthypoxic PAECs.
